Prick out the seedlings and plant them into individual pots when large enough to handle. Make sure that the bulb part of the plant is not covered with compost. Move the plants into a coldframe or unheated greenhouse, to acclimatize to outdoor conditions before planting out to final position. Plant 30-40 cm apart in rich, fertile soil.

Thin out if sown direct outdoors when seedlings emerge and keep the rows weed free. Water in the summer during dry spells. When the leaves start to yellow, allow the onions a further two weeks, then lift and store in a cool dry place.
